A collider observable QCD axion

TL;DR

This paper proposes a TeV-scale QCD axion model that is detectable at colliders, featuring unique decay signatures and additional particles, with theoretical motivations rooted in conformal dynamics and strong CP considerations.

Contribution

It introduces a novel TeV-scale QCD axion model with specific collider signatures and predicts new pseudoscalar color octets, linking axion properties to observable phenomena.

Findings

The model predicts a TeV-scale axion accessible at colliders.

It forecasts additional pseudoscalar color octets with determined properties.

The theory links the axion mass to the weak scale through conformal dynamics.

Abstract

We present a model where the QCD axion is at the TeV scale and visible at a collider via its decays. Conformal dynamics and strong CP considerations account for the axion coupling strongly enough to the standard model to be produced as well as the coincidence between the weak scale and the axion mass. The model predicts additional pseudoscalar color octets whose properties are completely determined by the axion properties rendering the theory testable.
